I realize people can enjoy collecting even if there is no potential for future value, I do myself. My original question was just whether or not the Old School Base Sets were rendered almost or completely worthless by the sketch hunting. I ask the question not because I care (or think others do) if their "investment" will appreciate, but because I think it has a potentially detrimental effect on the health of Old School going forward.
Let's say tons of boxes are bought by sketch hunters, with the packs or base sets being dumped on the market at a deep discount. Why would anyone like myself (who feels obligated to pick up a set or two, but really doesn't care about the inserts) buy Series 2 boxes, when I know I'll be able to pick up the base set or tons of packs ultra cheap?
Anyone with basic aspirations would have no reason to order boxes at all.
I guess it doesn't really matter as long as the boxes sell through whether its to sketch hunters or normal collectors, and the limited release makes this effect less severe than it was with the flashbacks, where the available quantity of base sets was so astronomical as to make them literally worthless.
